CURTAIN- FIXTURE.

E-PECIPICATION forming part of Letters Patent No. 332,907, datedDecember 22, 1885.

Application filed October 8,1885. Serial No. 179,299. (No model.)

To all whom it may concern.-

Beit known that I, WALLACE O. KELLY, of Hastings, in the county of Barryand State of Michigan, have invented new and useful Improvements inCurtain-Fixtures; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, which form apart of this specification.

This invention relates to certain new and useful improvements incurtain-fixtures; and the invention consists in the peculiar construc=tion, arrangement, and combinations of the various parts, all as morefully hereinafter set forth.

Figure 1 is an elevation of my improved device as hung up ready for use.Fig. 2 is a longitudinal section through the spool end. Fig. 3 is an endview of the same with adjusting-screw removed. Fig. 4 is adetail inperspective.

In the accompanying drawings, which form a part of this specification, Arepresents a curtain-roller, one end of which is provided with a rigidspindle or journal, a, designed to engage with a suitable hanger, B. Tothis roller the curtain O is tacked, as in the ordinary manner. Theopposite end ofthe roller A has secured to it a disk, D. E is an outerdisk, which is secured to this end of the roller by means of a screw,F,such screw passing through both disks and a cylindrical rubber spring,G, into the end of the roller. Upon the outer face of the disk E, andpreferably formed integral therewith, isa hub, H, portions of which arecutaway to form stops b, which are designed to engage with a spur ordetent, 0, formed in the opening in the lower end of the hanger I, thelatter being held in its proper position by the head of the screw F. Theup per ends of the hangers B and I are adapted to hook upon hooksJ,projecting from the window-frame, as shown in Fig. 1.

In practice, the parts being constructed and arranged as shown anddescribed, supposing the curtain to be rolled upon the roller and it isdesired to lower the curtain, this is accomplished by pulling down uponthe curtain, the roller turning upon its pivotal point a at one end, theinner disk, D, rolling with the curtain as well as the screw F, whichturns in the bearing in the lower end of the hanger I, the

disk E being prevented from turning by the engagement of one of thesestops 1) with the detent 0. To prevent the curtain from unrollingby itsown weight, the screw F is turned. in, so as to compress the rubbercylindrical spring G between the two disks, so that the frictionalcontact of such spring and the two disks will be sufficient to overcomethe weight of the curtain. Such being the case, it will readily be seenthat the curtain may be pulled down to any desired point, the frictionreferred to retaining it in its adjusted position.

To raise the curtainit'is merely necessary to pull down upon the cord K,which has been wound around the cylindrical spring between the disks asthe curtain was pulled down, which causes the stop b to disengage fromthe detent G, such stops in the rotation of the disk E sliding uptheinclined face of the detent 0. When the curtain has been raised orrolled up the desired distance, by releasing the cord the weight of thecurtain causes a retrograde rotation of the roller until one of thestops 1) again engages with the detent.

The tension or compression of the spring between the disks may beregulated by the screw F for heavier and lighter curtains.

It will be observed that in winding the curtain up the tendency is forthe roller to run to the forward end of the elongated opening in thehanger I, thejournal turning freely therein, while in the retrogrademovement of the roller thejournal runs to the rear end of such hanger,and engages with the detent of the hanger, preventing the curtain fromunrolling.

I am aware of the Patents Nos. 147,099, February 3, 1874, and 187,422,February 13, 1877, and make no claim to the constructions shown thereinas forming part of my invention.

I attach importance to my cylindrical spring G,interposed between thetwo disks, and forming a drum on which the cord is wound. The springthus serves a double function.

I am also aware of the Patent N 0. 243,465, in which a coiled spring isarranged around the spindle, and lay no claim to such construction. Thiscoiled spring does not form a drum on which the cord is wound, and whenthe loo cord is wound on the spindle and over said spring it interfereswith its operating asa tension-regulator. In my construction the windingof the cord on the spring in no wise inter feres with the usefulness ofthe same as a tenthe hanger I, having elongated opening andsion-regulator. detent c, of the roller A, disk D,se(-.ured there- I 5What I claim as my invention is to, disk E, having formed integraltherewith 1.
